Which HTTP status family does a code belong to
HTTP status codes are grouped by their hundreds digit: 2xx means success, 5xx means server trouble, and so on.
- 100-199 return 1, 200-299 return 2, 300-399 return 3, 400-499 return 4, 500-599 return 5.
- Any value outside those ranges, including negatives, returns 0.
httpFamily(status: int) → int
Go needs a compiler and Drill does not host one yet, so this page is the reference rather than an exercise: the problem, worked examples, and the solution in full. To type it out, the same problem runs in Python.
Where you start
func httpFamily(status int) int {
}Worked examples
| Call | Result |
|---|---|
httpFamily(200) | 2 |
httpFamily(404) | 4 |
httpFamily(503) | 5 |
httpFamily(100) | 1 |
Hint
Divide by 100 and check the result.
Reference solution in Go
func httpFamily(status int) int {
if status >= 100 && status <= 199 {
return 1
}
if status >= 200 && status <= 299 {
return 2
}
if status >= 300 && status <= 399 {
return 3
}
if status >= 400 && status <= 499 {
return 4
}
if status >= 500 && status <= 599 {
return 5
}
return 0
}
